US authorities have announced a multi-stage effort to interrupt digital fundraising tied to Hamas, reporting that more than $560,000 in cryptocurrency intended for the group has been taken into government custody.
The Justice Department said court-authorized actions also allowed the FBI to assume control of websites, servers, and related communication platforms used to solicit donations and attract supporters.
According to officials, the seized digital assets and online infrastructure were operated on behalf of Hamas’s military wing, the Al Qassam Brigades. Investigators described a fundraising model that mixed encrypted chats, a public website, and a rotating set of cryptocurrency addresses.
The group, they said, sought donations from supporters around the world and tried to move money outside conventional banking channels.
Hamas has been designated a foreign terrorist organization by the United States.
The $560,000 figure was not the product of a single raid.
Court records released with the announcement show three cryptocurrency seizure warrants executed on March 25, June 25, and October 10, 2025.
Agents used information from multiple human sources to identify wallets, follow the flow of funds across blockchains, and take control of addresses and exchange accounts tied to the campaign.
An earlier action in March 2025 had already recovered about $201,400 from a network that authorities said had processed more than $1.5 million since late 2024.
Later warrants expanded that recovery.
In parallel, the FBI’s Albuquerque Field Office moved against the digital storefront that supported the fundraising.
Agents seized domains and servers connected to AlQassam.ps, the main website associated with the Al Qassam Brigades.
Taking over that infrastructure did more than take a site offline.
Officials said it allowed investigators to intercept incoming cryptocurrency transfers that supporters still attempted to send after the group’s public-facing channels had been compromised.
Separate court orders in July and August 2026 covered those infrastructure seizures.
The operation also produced a large volume of contact data.
After gaining control of the websites and related communications systems, the FBI obtained information on thousands of people who had reached out online in an effort to donate, whether through digital assets or more traditional payment methods.
Officials said that intelligence will be used in ongoing counterterrorism work.
US Attorney Jeanine Ferris Pirro framed the case as a warning that terrorist fundraising networks are neither secure nor beyond reach.
FBI Cyber Division Assistant Director Brett Leatherman added that Hamas had used cryptocurrency and online platforms to raise money globally, and that the bureau would keep using its legal authorities to intercept illicit funds.
Court filings describe a cat-and-mouse pattern.
Donation addresses were swapped frequently. Supporters were directed through encrypted group chats and email accounts.
Blockchain tracing, human sources, and later control of the group’s own web infrastructure allowed investigators to follow money even as addresses changed.
Filings referenced assets including Tether on the Tron network as well as other virtual currencies and exchange accounts.
Officials estimated that the broader fundraising pipeline had received millions of dollars over time, far more than the amount ultimately seized in these particular warrants.
The announcement is part of a longer US campaign against Hamas financing that has included earlier crypto seizures and civil forfeiture actions.
Authorities argue that taking both money and the platforms used to collect it can disrupt recruitment and fundraising at the same time. Whether the donor records lead to additional cases remains a matter for future investigations. For now, the Justice Department presents the seizures as evidence that digital anonymity is not a reliable shield for terrorist finance.
